Hi, Anders.

I'm curious about the difference between Andy's remark "entirely normal"
and your remark "slow and the resolution wrong with the generic driver".
Is it related to VGA vs HDMI or perhaps to Andy apparently running
Ubuntu 10.04LTS ("LinuxCNC 2.5 LiveCD") and you running 12.04LTS?
Also, I have yet to run a program that obviously runs better in 64-bit
versus 32-bit Linux. Is 64-bit really a criterion for you?
Comments?

Aside: Intel has preparing to launch Valley View in 2013. From
Phoronix.com, "Valley View will see full Linux support and is looking to
be fantastic: an Atom SoC with Ivy Bridge graphics." The winds of change
keep on blowing.
Aside**2: I understand why these boards are showing up with HDMI but the
HDMI connector is lousy physically. I have enough trouble with
intermittent connections to my TV as the cable is flexed. I could
imagine this connector being a nightmare in a machine shop. Too bad the
industry felt the need to abandon reliable but more costly solutions.
